Waves and Refraction, Diffraction, and Reflection

diffraction is......?

• the peaks and troughs of a wave

• when in a transverse wave the particles move from side to side at right angles to the direction of travel of the wave.

• When a wave spreads out as it travels through a gap or past the edge of an object.

• In a wave where the particles move forwards and backwards along the direction of travel of the wave
